Tylar Murray commented on AIRFLOW-1305:
---------------------------------------

After running into this myself using airflow v1.9.0 and confirming that the 
issue was with the dag table in the database. In general the cause seems to be 
that the scheduler and webserver are unable to reconcile differences between 
the database and the filesystem. The steps I would suggest to resolve this are:
 # check permissions on dag definition files to ensure airflow can read the 
files
 # restart scheduler and webserver in hopes they can work things out after 
restart
 # `airflow initdb` to reset the dag table using the filesystem 

Anecdotally, `initdb` doesn't affect any dags that still exist, but it will 
clear dags not found on the filesystem and add ones on the filesystem but 
missing from the database.
